Embodiment 1

[0030] Embodiment 1: The compound shown in formula (I) is the synthesis of 2-formyl-8-hydroxyquinoline trihydroxyaminomethane Schiff base ligand

[0031]

[0032] The specific synthesis method is as follows: Weigh 0.0173g (0.1mmol) of 2-formyl-8-hydroxyquinoline and dissolve it in 5mL of methanol, and dissolve 0.0121g (0.1mmol) of trishydroxymethylaminomethane in 5mL of acetonitrile. The methanol solution of 8-hydroxyquinoline was slowly added to the acetonitrile solution of trishydroxymethylaminomethane. At this time, the mixed solution was red, and it was put into a magnet and stirred for 30 minutes. The solution was light yellow, and a solution containing ligand was obtained. .

Embodiment 2

[0033] Embodiment 2: the compound shown in formula (I) is the synthesis of 2-formyl-8-hydroxyquinoline trihydroxyaminomethane Schiff base ligand

[0034] Repeat Example 1, the difference is that the amount of methanol is changed to 2mL, the amount of acetonitrile is changed to 4mL, and the reaction time is changed to 20min.

Embodiment 3

[0035] Embodiment 3: tetranuclear dysprosium cluster [Dy 4 (C 14 h 14 N 2 o 4 ) 4 (CH 3 COO) 4 (CH 3 Oh) 2 ]·2H 2 Synthesis of O

[0036] Weigh Dy(CH 3 COO) 3 ·6H 2 O (0.2mmol, 91.2mg) was placed in a glass bottle with a cover, and the ligand solution prepared in Example 1 was sucked with a disposable rubber tip dropper (1mL ligand solution contained methanol 0.5mL, acetonitrile 0.5mL, Ligand (0.1mmol) was added to the glass bottle, and then 0.25mL of methanol and 1.75mL of acetonitrile were added to it, so that the volume ratio of methanol and acetonitrile in the mixed solvent was 1:3, and then 45μL of triethylamine was added to it after dissolving , shake gently until the precipitate disappears (the pH of the solution at this time is 7.3), then wrap the mouth of the bottle tightly with aluminum foil, cover the bottle cap, place the glass bottle at 60°C for 24 hours, take it out, and wrap it with cotton wool After the glass bottle was cooled to room temperature,...

The invention provides two methods for synthesizing the tetranuclear dysprosium cluster compound; the methods are simple and have relatively high yield and good repeatability. The applicant researches and finds out that the cluster compound has a single molecular magnet behavior and can be used for preparing magnetic materials.

Description

technical field [0001] The invention relates to a tetranuclear dysprosium cluster compound based on 2-formyl-8-hydroxyquinoline trihydroxyaminomethane Schiff base, a synthesis method and an application thereof, and belongs to the technical field of magnetic materials. Background technique [0002] Due to their structure and the unique properties of rare earth ions, rare earth complexes have excellent optical, electrical, and magnetic properties, and have broad application prospects in the fields of magnetic materials, optical sensors, and molecular recognition. Compared with transition metals, rare earth ions are often used to construct single-molecule magnets due to their large anisotropy, and their complexes often have excellent magnetic properties. For example, several high-energy barrier complexes reported so far are Rare earth Dy(III) clusters. In view of the excellent magnetic properties of their complexes, scientific researchers have reported that many rare earth com...
